Good news, everyone. You can feel free to make plans for the future — a new analysis of the sun finds that it won’t burn the Earth to a crisp as early as previously thought. Yes, you have several hundred million extra years to not exist before the Earth becomes a lifeless, roasted husk.

As the sun ages, it is fusing hydrogen into helium, and helium into heavier elements like iron. As it burns through the supply of hydrogen, the sun gets progressively warmer until it eventually expands into a red giant. Before that happens, it will get warm enough that Earth’s oceans are vaporized and life extinguished. Scientists have long expected that was going to happen in 600-700 million years, but Eric Wolf, a doctoral student at the University of Colorado says the old model is too simple.

By factoring in the effects of cloud cover, carbon dioxide, and varying environmental factors around the globe, Wolf and his colleagues have created a more advanced model of the future climate. While the Earth will warm considerably, it should still have liquid water capable of supporting life for about 1.5 billion years, according to the new analysis. Although, the average surface temperature will eventually reach 40°C — pretty uncomfortable for anything resembling humans.

This reevaluation of the effect stars can have on Earth-like planets could also be of use to astronomers who are busily scanning space for potentially habitable worlds. If slightly more heat from a star doesn’t necessarily mean a lack of water, the habitable zone of alien solar systems could be expanded. Although, the clock is ticking — no planet will survive forever.
